Manaʻo kōkua koʻikoʻi:Loaʻa i ka mōlina puka makani o nā ʻaoʻao FRP kekahi mau pono kūikawā ma mua o ka lāʻau a me ka vinyl, a ʻoi aku ka paʻa. ʻAʻole lākou e hōʻino maʻalahi ʻia e ka vinyl e like me ka lā, a hiki ke pena ʻia me ka hana kaumaha.

FRPLoaʻa i nā mōlina puka makani kekahi mau pono kūikawā ma mua o ka nui o ka lāʻau a me ka vinyl, ʻoi aku ka paʻa. ʻAʻole lākou e hōʻino maʻalahi ʻia e ka vinyl e like me ka lā, a hiki ke hoʻoluʻu ʻia i nā kala kaumaha, e ʻoi aku ka kūpono a ʻoi aku ka nani ma mua o ka vinyl. Hoʻohana kekahi mau papa aniani i ka lāʻau paʻa e kāʻei i ka loko aloha i ʻike ʻia e like me ke mōlina lāʻau. ʻO ka pono o ka ikehu o ka puka makani e hilinaʻi nui ʻia ma ka pono o ka puka makani. ʻO nā waiwai insulating o ka mea mōlina ponoʻī he mea nui ia, a i ka wā e ʻae ai ke ʻano i ka ea e kahe ma loko, ua hoʻemi nui ʻia ka pono o ka puka makani. ʻOi aku ka maikaʻi o nā insulators lāʻau, plastic, a me fiberglass ma mua o ka metala. Ma ke ʻano o ka pono o ke ʻano, maikaʻi nā mōlina lāʻau inā loaʻa iā lākou ka mālama kūpono FRP, FRP pultruded profiles a mefiberglassnoho nā mōlina i ke kūlana maikaʻi.

A laila, e lawe wau iā ʻoe e ʻike i nā ʻano o nā ʻano FRP pultrusion i huki i ka nānā hou aku:

He mea anisotropic ka FRP; ʻo ka mea hao ma ke ʻano laulā he ʻelua pae o ka elastic deformation a me ka plastic deformation ma lalo o ka hana o ke kaumaha, ʻoiai ʻo FRP maʻamau ʻaʻohe pae plastic deformation maopopo. No laila, i ka hoʻolālā a me ka hoʻāʻo ʻana i ka hana ʻana o nā huahana FRP, ʻaʻole hiki ke hoʻohana ʻia ke ʻano metala.

Nā ʻano hana o FRP:ma ke ʻano he hui pū ʻana oʻili aniani a me ka resinʻōnaehana, hana ʻia ka hapa nui o lākou i ka resin thermosetting, a ʻaʻole hiki ke hana ʻia i loko o nā huahana like ʻole me nā paipu, nā papa, a me nā ʻano ʻē aʻe e like me nā metala a i ʻole nā resin thermoplastic. ʻO ka hapa nui o nā plastics i hoʻoikaika ʻia i ke aniani fiber i hana pololei ʻia i loko o nā huahana e pono ai. Nui nā kaʻina hana hoʻokumu, ʻo ia hoʻi me ka hoʻopaʻa lima ʻana, ka hoʻoheheʻe ʻana, a me ka wili ʻana.
